Nigel Farage, Douglas Carswell and Mark Reckless have responded to the Government's failure to offer the Commons a vote on the European Arrest Warrant.
UKIP Leader Nigel Farage said: "The failure to offer the Commons a vote, and thus the British public a say on the European Arrest Warrant, is a farce.
"The Government has treated British democracy with customary contempt.
"It's difficult to believe a word this Government says on any issue."
UKIP MP Douglas Carswell: "David Cameron promised a vote on this issue in the Commons. His Whips tried to play it clever and fix procedure. It has backfired spectacularly.
"Government Whips had to summon Cabinet Ministers back to rescue themselves from their own chaos."
UKIP's Mark Reckless said: “The Home Affairs Select Committee agreed unanimously that Parliament should vote on an amendable motion when deciding whether to opt in to 35 EU Justice and Home Affairs measures and put the European Court of Justice in charge for the first time. We also demanded that there should be a separate vote on the European Arrest Warrant. The government's refusal to respect that advice ended in a procedural shambles tonight. It showed contempt for Parliament, the public, and democratic process. Voters in Rochester and Strood will have their chance to give their judgement next week and the country will follow next May."
